December typically marks the start of the dry season on Koh Chang, an island in the Gulf of Thailand. This period is characterized by lower humidity, sunshine, and calm seas, making it an ideal time for outdoor activities like swimming, sunbathing, and watersports. Average temperatures generally range from the mid-20s to low 30s degrees Celsius (mid-70s to high-80s Fahrenheit).
The favorable climate during this month contributes significantly to the island’s appeal as a tourist destination. The dry season offers optimal conditions for exploring Koh Chang’s diverse natural beauty, including its lush rainforests, cascading waterfalls, and vibrant coral reefs. Historically, this period has aligned with peak season, attracting visitors seeking a tropical escape during the northern hemisphere’s winter months. This influx of tourism benefits local businesses and the island’s economy.
